Control Components

Ring

A control evoking the focus ring on a proper camera lens.

Similar in functionality to a <Slider>.

Integrates the Ring control from Tweakpane-creator Hiroki Kokubun's CameraKit plugin.

Usage outside of a <Pane> component will implicitly wrap the ring in <Pane position="inline">.

Note that Svelte Tweakpane UI embeds a functionally identical fork of the plugin with build optimizations. The fork also changes the package name from @tweakpane/plugin-camerakit to @kitschpatrol/tweakpane-plugin-camerakit for consistency with other plugins.
